The overall and transmission device design of 3809 mechanical upright kiln
Abstract: There are two main difficulties of mechanical upright kiln presented both on technology and on process. First, the hot working of the kiln is unsteady, which seriously affects the physical performance of the cement; second, the output of the single-kiln is low, which cannot adapt to the intensified development situation in various professions. As a result, 3809 mechanical upright kiln is appeared in this situation. The transmission device plays a vital role in the whole configuration of the kiln. On the basis of comprehensive investigation and study, the present production situation has been analyzed and the transmisson device has been designed in order to enhance transmission efficiency of the kiln in the cement production, satisfy meet production process and productivity demands. By using optimization method, the definite transmission ratio,ball gear and pinion gear have been designed at first.Then the axis structure and intensity examination computation have been completed too. After determining the kiln rotational speed, chooses the reasonable lubrication form. Moreover, the large vertical spindle is the main part in the transmission, it impetuses the cone type to discharge grate at a low speed and withstands huge load, which is the key to ensure the normal work of the kiln. This calls for high reliability, good stability and reasonable economical efficiency. By comparing several plans, the optimization method was confirmed on the choice of bearing, thus increases the transmission stability and the service life of the kiln, enhancing the kiln operating efficiency greatly.It is smooth and reliable in operation,convenient in installation and maintenance.
